iCooler IV Cooling Technology

iCooler IV features a high performance dual slot cooler. Massive amount of cool air is drawn from the central cooler to cool down the internal fins directly. Heat from the 4850 GPU can rapidly transfer to internal fins that extend under the cooler. The optimized iCooler fan design allows air flow to pass in and out and removes heat effectively. With efficient central powerful cooling, the iCooler IV offer excellent cooling and noise control performance for the system.

Key Features

• Faster: Heat transfers rapidly out of GPU and reduces temperature instantly
• Cooler: Award-winning and performance leading iCooler technology with 10°C lower than reference cooler
• Quieter: iCooler IV excel in noise management. It's extremely quite and noise level is less than 28dB
